-=head1 NAME
-
-base - Establish an ISA relationship with base classes at compile time
-
-=head1 SYNOPSIS
-
-    package Baz;
-    use base qw(Foo Bar);
-
-=head1 DESCRIPTION
-
-Unless you are using the C<fields> pragma, consider this module discouraged
-in favor of the lighter-weight C<parent>.
-
-Allows you to both load one or more modules, while setting up inheritance from
-those modules at the same time.  Roughly similar in effect to
-
-    package Baz;
-    BEGIN {
-        require Foo;
-        require Bar;
-        push @ISA, qw(Foo Bar);
-    }
-
-C<base> employs some heuristics to determine if a module has already been
-loaded, if it has it doesn't try again. If C<base> tries to C<require> the
-module it will not die if it cannot find the module's file, but will die on any
-other error. After all this, should your base class be empty, containing no
-symbols, it will die. This is useful for inheriting from classes in the same
-file as yourself, like so:
-
-        package Foo;
-        sub exclaim { "I can have such a thing?!" }
-        
-        package Bar;
-        use base "Foo";
-
-If $VERSION is not detected even after loading it, <base> will define $VERSION
-in the base package, setting it to the string C<-1, set by base.pm>.
-
-C<base> will also initialize the fields if one of the base classes has it.
-Multiple inheritance of fields is B<NOT> supported, if two or more base classes
-each have inheritable fields the 'base' pragma will croak. See L<fields>,
-L<public> and L<protected> for a description of this feature.
-
-The base class' C<import> method is B<not> called.
-
-
-=head1 DIAGNOSTICS
-
-=over 4
-
-=item Base class package "%s" is empty.
-
-base.pm was unable to require the base package, because it was not
-found in your path.
-
-=item Class 'Foo' tried to inherit from itself
-
-Attempting to inherit from yourself generates a warning.
-
-    use Foo;
-    use base 'Foo';

-
-=head1 HISTORY
-
-This module was introduced with Perl 5.004_04.
-
-=head1 CAVEATS
-
-Due to the limitations of the implementation, you must use
-base I<before> you declare any of your own fields.
